On Baptism, Against the Donatists.
Chapter 19.—32. Felix of Bagai said: As when the blind leads the blind, both fall into the ditch,
Chapter 37.—71. Libosus of Vaga said: The Lord says in the gospel, ‘I am the truth ’
Chapter 10.—18. Likewise another Felix of Marazana said: There is one faith, one baptism,
Chapter 14.—26. Aymnius of Ausuaga
Chapter 26.—50. Also another Lucius of Membresa said: It is written, ‘God heareth not sinners.’
Chapter 46.—90. Litteus737 Some read Licteus; not unlikely the bishop of Cypr. Ep. lxxvi. of Gemelli738 Gemelli was a Roman colony in ecclesiastical province of Numidia. said: "‘If the blind lead the blind, both shall fall into the ditch.’739 Matt xv. 14. Since, therefore, it is clear that heretics can give no light740 Illuminare; baptism being often called φωτισμός. to any one, as being blind themselves, therefore their baptism is invalid."741 Conc. Carth. sec. 82.
91. Neither do we say that it is valid for salvation so long as they are heretics, just as it is of no value to those murderers of whom we spoke, so long as they hate their brethren: for they also themselves are in darkness, and if any one follows them they fall together into the ditch; and yet it does not follow that they either have not baptism or are unable to confer it.
